Answer AND Explanation:
Fossil fuels are substances that are combusted to provide energy. They include coal, natural gas and oil. Nitrogen(IV) oxide is a byproduct of all fossil fuel combustion that contribute to acid rain and ground-level ozone. Nitrogen (IV) oxide can burn lung tissue making people more susceptible to asthma, bronchitis, and other chronic respiratory diseases. When gases like sulphur (IV) oxide and nitrogen (IV) oxide mix they form acid rain and other precipitation when dissolved in water. Acidic precipitation increases the acidity of lakes and streams, which can be harmful to fish and other aquatic organisms.
Excess production of CO2 by industries results in green housse effect which causes global warming. The gases are also poisonous to the respiratory system causing breathing difficulties, eye irritation and headache.
Tortoises are larger on the islands, where there are less predators
Flinches are different colors depending on their diet yet they are still anatomically similar
Animals are different within species and mate all the way to the point where some must die
The correct answer of the given question above would be option C. The best option that defines sustainable fishing practices is that, harvesting practices that do not reduce the potential for future harvests. Sustainable fishing guarantees that the population of the ocean and freshwater wildlife is still present over time. Hope this answer helps.
In rheumatoid Arthritis patients, NK cell levels were abnormally elevated, possibly due to high serum levels of IL-2.
Rheumatoid arthritis (RA), is an autoimmune disease that means our own immune system attacks self healthy cells in the body by mistake, causing inflammation (painful swelling),mainly attacks the joints.
The given study is to investigate the relationship between serum interleukin-2 (IL-2) levels and disease activity.
This study also showed the relationship between absolute numbers of peripheral lymphocyte subsets, autoantibodies, and associated cytokines in patients with rheumatoid arthritis (RA).
The results showed that the number and percentage of NK cells were positively correlated with serum IL-2 levels so, IL-2 can be a reason for elevated level of NK cells
